A survey of NASTRAN improvements since level 15.5
Several improvements and capabilities were developed and installed in intermediate levels and are being analyzed and evaluated. A survey of current improvements to the program is presented which includes static analysis with differential stiffness rigid format, normal modes with differential stiffness rigid format, the TRIAAX and TRAPAX elements, the CNGRNT feature, fully stressed design, element strain energy and grid point force balance, and complex modal displacement plots
Issues in corporate governance
On September 29, 2002, William J. McDonough, President of the Federal Reserve Bank of New York, delivered the William Taylor Memorial Lecture in Washington, D.C., at an event cosponsored by the William Taylor Memorial Fund and the Group of Thirty, a private, international consultative group on economic and monetary affairs. In his lecture, Mr. McDonough describes the actions already taken by private and public sector groups to strengthen corporate governance and accounting standards and identifies areas where reforms are still needed.Corporations - Finance ; Accounting ; Risk management ; Executives - Salaries

Radiogenic power and geoneutrino luminosity of the Earth and other terrestrial bodies through time
We report the Earth's rate of radiogenic heat production and (anti)neutrino
luminosity from geologically relevant short-lived radionuclides (SLR) and
long-lived radionuclides (LLR) using decay constants from the geological
community, updated nuclear physics parameters, and calculations of the
spectra. We track the time evolution of the radiogenic power and luminosity of
the Earth over the last 4.57 billion years, assuming an absolute abundance for
the refractory elements in the silicate Earth and key volatile/refractory
element ratios (e.g., Fe/Al, K/U, and Rb/Sr) to set the abundance levels for
the moderately volatile elements. The relevant decays for the present-day heat
production in the Earth ( TW) are from K, Rb,
Sm, Th, U, and U. Given element concentrations
in kg-element/kg-rock and density in kg/m, a simplified equation to
calculate the present day heat production in a rock is: The
radiogenic heating rate of Earth-like material at Solar System formation was
some 10 to 10 times greater than present-day values, largely due to
decay of Al in the silicate fraction, which was the dominant radiogenic
heat source for the first Ma. Assuming instantaneous Earth formation,
the upper bound on radiogenic energy supplied by the most powerful short-lived
radionuclide Al ( = 0.7 Ma) is 5.510 J,
which is comparable (within a factor of a few) to the planet's gravitational
binding energy.Comment: 28 pages, 6 figures, 5 table
